Parsing string variables

Hi!
I want to know if there is a way for me to parse a string variable containing a comma-separated list. Then using a loop, remove each element from the list alongwith the comma separator until the string variable becomes empty.

Thank you.

In ksh,

Code:

list="one,two,3333   3333,four,five"
echo "$list" | tr '[,]' '[\n]' | while read item 
        echo "$item"
done

Sounds like homework to me.

Here is a start:

Code:

var="a,big,bus full of,people,went,home on sunday"
echo "$var"| awk '{z=split($0,flds,",") 
                   for(i=1;i<=z;i++) 
                   print flds[i]}' 
var=""
